AUTOMATIC SEAL-TRAP FOR WASH-BASINS AND WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 320,708, dated June 23, 1885.

Application filed June 25, 1883. (N0 model) f0 all whom it may concern Be it known that I, WILLIAM D. SOHUYLER, of the city, county, and State of New York, have invented a new and Improved Automatic Seal-Trap for WVash-Basins and Water-Closets, of which the following is afull, clear, and exact description;

My invention relates to improvements in automatic seal-traps for wash-basins and water-closets; and it consists in the peculiar construction and arrangement of the parts, as hereinafter more fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l representsin rear View and partly in section a wash basin or bowl fitted with my improvements. Fig. 2 is a verticalsectional elevation at right angles to Fig. 1; and Fig. 3 is an enlarged detail sectional elevation, specially designed to show the water-inlet and waste or discharge valves and their immediate connections.

The letter (t represents a wash bowl or basin of the usual or any approved form, and fitted with. the discharge plug or stopper 1) and overflow channel or duct 0, leading from the usual basin-apertures,- d, to the waste-pipe 0, through any suitable screw-plug and nippleconnections, f, and valve-casing g, fitted with a straight-way plug or other suitable valve, h, which has connection, by extensions of its stem, with a yoke lever or arm, a', carrying a suitably-connected weight, j, of sufficient gravity to maintain the automatic closure of the valve h, as in Fig. 3, any approved water-seal trap, is, being provided between valve 9 hand the waste-pipe c.

Ihave here represented the basin a as supplied by both hot and cold water from the nozzles or faucets ll, through water-inlet pipes at n, which connect with the casing or jacket 0 of inlet'valves of peculiar construction, as next described; and as the water-flow to either hot or cold water faucets is controlled by similarly-constructed and like-operating devices, the same description will suffice for either or both the faucets and connections, as follows:

For a convenient and substantial support for these water-inlet valves and connections, I prefer to employ a rectangular frame, p, located along the back of the basin a, and se cured to the supporting-frame q at its base in any suitable manner.

The valve-casing 0 is fitted with the transverse divisionwall or partition T, which has an annular ring, 8, surrounding the central aperture for the close-fitting body or central portion, t, of the valve to to slide in, said apertured partition 1' and valve a dividing the casing 0 into an upper chamber, 2;, anda lower chamber, 10, which connect, respectively, with the pipe m, leading to the faucet Z, and'the pipe at, leading from the water-supply.

To provide for the economical manufacture of the casingo, I propose to make its main body portion in cylindrical form and of uniform diameter throughout, aside from the nipple connections of the pipes m n, which nipples kc may either be cast with or screwed into the main body of the casing o, as desired, which construction of the casing enables me to rapidly screw-thread its opposite ends externally or internally for a secure connect-ion with the base-plate of frame 1) by screwing the easing into or over .a collar, y, formed on or fixed to frame 1) at the bottom, and to receive at its top the screw-cap and stuffing-box a b, through which the main stem 0 of valve It moves with a water-tight joint. The frame 12 also has a tubular extension, 01, centrally of the bore of easing 0, to receive the lower extension, c", of the stem of valve to, which is thus supported above and below for longcontinued precision of action in insuring a tight valve-closure for completely shutting off the water-supply from pipe m, the coiled spring 6 below the valve aiding its prompt seating, and the packing f insuring a watertight joint of the casing o with the base 1), and the Valve a may or may not be fitted with any approved packing, y, where it seats itself upon the ring 8.

Above the body portion 16 of valve to the head or upper portion of the valve is tapered upward at t to the diameter of the valve-stem c, or thereabout, for gradual inlet and quick cut-off of the water with reference to the opening of the basin discharge-valve h, as hereinafter described.

As a means of operating valve u, I rigidly connect its stem 0' by a screwjoint or otherwise with the yoke or shackle h, which has tongues or feathers t,-fitted to slide vertically in ways or grooves j of a collar or bracket bearing, which is fixed suitably to the side of framep, so as to guide the shackle h in alignment; with the valve-stem o c as the shackle is moved to open or close the valve u by the rod Z, which is held from lengthwise movement by the collars m, fixed to the rod above and below the top plate of frame or other convenient support. The rod Z has a double or triple cut screw-thread, a, which is fitted in a serew'tapped hole in the head of shackle It, so that a turning of the red by its handle 0, located conveniently above the. ba sin a, will cause a quick and positive movement of the valve u in controlling the watersupply.

Vith a system of valves and operating devices constructed as above described, I propose to connect the valve h in a manner to automatically open it when water is supplied to the basin a from either faucet or both faucets Z, and also to allow of the free discharge of the contents of the basin independently of the operation of the valves a, which I accomplish by means of the levers p, fulcrumed at q in rods or suports r, preferably secured by bolt ends and jam-nuts s to the top plate of frame 1), the levers 1) being yoked about the valve-stems c to bear by their short arms against the lower ends of the traversing shackles h, and their long arms being attached by the chain or other suitable flexible connections, t, with the yoke or aunt of the valve h. The flexible connection t permits the valve hto be opened by drawing upon the rod 11,, which connects, by a chain or cord, 0 with the valve-arm z, and this rod a is connected also by the chain w with the basin-stopper b, for removing the stopper to permit discharge of the contents of basin a simultaneously with the opening of valve h by rod to, while also allowing the stopper 1) to be removed by chain w without drawing upon the rod to when it is desired to open the valve h by opening the inlet-valves u, or either of them.

The operation is as follows: WVhen either or both of the handles 0 are moved to cause the correspondingshackle, h, to move downward, its connected valve to will be opened; but as the bearing of lever 19 on the lower end of shackle h is constant, and as the portion t of the valve u forbids inlet of water through the valve until the portion 15 of valve to passes opposite to or below the lower edge of ring .9, the valve h will be opened in advance of the inflow of water to the basin a, so as to prevent the free escape of water through the overflow-apertures (Z and channel a, and through the valve h and waste-pipe e at such times and without danger of flooding the premises by overflow from the top of the basin a. It will also be noted that the taper of the portion t of the valve permits but a graduallyincreasing inflow of water, thus permitting a considerable increase of opening of the valve h in advance of the full supply from the pipes 02, and also affords a quick closure of valve u to cut off the inflow of water from pipe 11 in advance of the closure of the valve h, which will thus remain open longer than is necessary to pass all the Water admitted to the basin a, and in practice it is proposed that the area of opening of discharge-valve It shall exceed the combined areas of the openings of the supply-pipes a or their inlet -valves u. Drawing on the rod u will open valve h without affectingthe water-inlet valves to, and stopper b may be withdrawn either by pulling the rod u or chain w directly, as above stated.

It will be understood that the rod to is simply the terminal continuation or handle of the chain c.

It will be understood that the shackleh may be grooved, and its bearing is, be tongued for guides to the shackle instead of the reverse arrangement above described, and also that the construction and positive action of the parts of myimprovements permit their use in either the vertical position shown, or in the horizontal position, or in intermediate positions, as the necessities of the case shall demand, the connections to the valve It being in any case easily made and operated. Neither do I limit myself to the use of a valve h herein shown, or to the precise arrangement of the details of the apparatus as above described, as these may vary within the scope of my invention, which not only provides against overflows of water, but at the same time effectually seals the basins or water-closets to which they may be applied against the escape of foul air and gases so injurious to health.

It will be observed that the lever 19, which connects at one end with the stem of the inletvalve, is connected at its outer end with the lever i of the discharge-valve by means of a chain, it, thus forming therewith a flexible connection. As a result of this connection, the discharge-valve may be operated both in conjunction with the inlet-valve and also independently of the inlet-valve. Y Vhen the inlet-valve stem is pushed down, the dischargevalve will be opened, as before described, and will automatically close when the inlet-stem is released.

WVhen it is desired to open the dischargevalve independently of the inlet-valve, the rod u is raised,which draws the chain c and opens the discharge-valve without moving the inletvalve. On releasing the rod to the dischargevalve automatically closes. The rod u is simply the handle or upward continuation of the chain c.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The two separate flexible connections t c and the rod w, in combination with the lever t of the automatic discharge-valve, and the leverp of the inlet-valve stem, as shown and described, whereby the discharge-valve may be operated either in conjunction with or indepengently of theinlet-valve, as desired, as set fort 2. The combination, with the operating-lever of a dischargevalve of a wash-basin or other vessel, of the stem 0 of an inlet-valve, provided with a sliding shackle, h, and a lever, 1), connected at one end to the inlet-valve stem, and secured at its opposite end by a flexible connection to the operating-lever of the discharge-valve, substantially. as shown and described.

3. The combination, with the valve h, arranged in the waste-pipe, and the lever 2', connected to said valve and oarryinga Weight, j, on its free end, of the inlet-valve t,valve-sten1 c, the sliding nut-shackle h on the upper end of the valve-stem, the rod Z, having its lower end screw-threaded, and the lever h, having its short arm engaging the valve-stem of the inlet-valve, and its long arm connected by a flexible connection'with the lever i, substantially as herein shown and described.

4. The combination, with the frame 1), the guide-b racket 70, provided with the ways j, the shackle-nut h, secured to the inlet-valve stem 0, and provided with the tongues t" and the rod Z, of the support 1", the lever 19', the chain 1?, the lever t, the weight f, and waste-valve 72, substantially as herein shown and described.
